The previous Red Mountain hike is rather long and starts close to the west end of Red Mountain. Now, there’s a new Red Mountain hike and it is shorter and easier to access. You can find the Red Mountain East Hike at this link. From the top of Red Mountain, you can view the Red Mountain American Viticultural Area. You also have some other great views. I was on top the other day and saw these amazing views of the fog rolling off the Horse Heaven Hills!
You can also get a great view of Mount Adams on a clear day as you can see over my shoulder in this picture below.
